Preferably, the filter member is detached from the sealing plug. During operation, a blood sample from a patient is received in a blood receiving area defined in the syringe barrel, while displaced air passes through the filter member and is substantially contained between the filter member and the sealing plug.
Patent CA-2229175-A1 (CA)
Inventor: RAZ RYAN S
IPC: G02B21/24
Filed: 1998-02-06
Abstract: An automated focus system comprising an intelligent controlled electro-mechanical actuation system for manoeuvring a microscope lens. The focus system brings a stained biological material into optimal focus for image acquisition. The automated focus system is operable without human intervention and utilizes a merit function based on the "texture" of a dark stained biological material in the field of view of the microscope objective. The system utilizes a maximization procedure using a feedback technique related to the merit function in order to control the position of the objective lens. The merit function, in turn, is based on a series of calculations performed on a set of digitized images captured at different focal positions. The use of an intelligent control routine to issue instructions to the motion control system allows the device to avoid the usual focus and pitfalls associated with microscopic image capture. The automated focus system also includes a focus mapping method which is particularly suited to monolayer specimens. The focus mapping method generates a mapping of the surface of the microscope slide which is then used to predict the optimal focus position at any point within the mapped region.

Title: Method and apparatus for information processing, computer readable medium, and authoring system
Inventor: SUZUOKI MASAKAZU
IPC: G06F9/445
Filed: 1998-03-26
Abstract: Data sequentially read from a storage device, such as a CD-ROM, in which program data and moving picture data are alternately recorded, is divided into program data and moving picture data by a demultiplexor.  The moving picture data is stored in an image data storage region of a main memory.  The moving picture data is then expanded by an MPEG decoder and is transferred to a decoded image buffer, and is further transferred to a frame memory of a graphic processing unit.  Every time moving picture data for one frame is transferred to the frame memory, it is converted into a video signal and output.  Accordingly, the loading time for the program data is decreased even though the moving picture data is reproduced while the program data is being loaded.

Patent CA-2235834-A1 (CA)
Title: Receiver for an optical communications system and method for operating such a system
Inventor: PFEIFFER THOMAS
IPC: H04B10/43
Filed: 1998-05-25
Abstract: A receiver is disclosed for receiving coded optical signals in an optical asynchronous communications system using a CDMA method based on periodic spectrum encoding. It has a first optical detector unit (PD1) and a second optical detector unit (PD2) which are preceded by a first periodic optical filter (Rx1) and a second periodic optical filter (Rx2), respectively. The roundtrip time of the second filter (Rx2) is shifted by approximately one quarter of the lightwave period of the received signal with respect to the roundtrip time of the first filter (Rx1). The inputs of the filters (Rx1, Rx2) are connected to the communications system through an optical splitter (KOP). The amplitudes of the outputs of the two filters are squared by means of two squarers (Q1, Q2) and added by means of an adder (AD). This makes the receiver (R) less sensitive to any drift of the filter transfer function.

Title: Laser drilling processes for making fabric and film forming devices
Inventor: JAMES WILLIAM A
IPC: B23K26/08
Filed: 1996-02-22
Abstract: Support members and method of forming support members for use in producing nonwoven fabrics, especially tricot-like nonwoven fabrics, and films. A topographical support member includes a body having a top surface comprising a pattern of a plurality of peaks and valleys and a plurality of apertures.      The apertures have a conical top portion that is surrounded by a cluster of the peaks and valleys. The center line to center line spacing of adjacent apertures is less than the major diameter of the conical top portion of the apertures.  The topographical support member is formed in a defocused process by focusing a laser beam so that the focal point is below the top surface of a starting work-piece and drilling with the laser beam the predetermined pattern of tapered apertures. The pattern of tapered apertures forms the cluster of peaks and valleys surrounding each aperture on the top surface of the resulting support member. A smooth, flat surface support member is formed by focusing the laser beam at the top surface of the workpiece or by adjusting the center line to center line spacing of apertures formed by the defocused process so that no peaks or valleys result. A perforated film or nonwoven fabric can be formed using the smooth surface support member.

Patent CA-2245820-A1 (CA)
Title: Distortion penalty measurement technique in optical systems based on signal level adjustment
Inventor: KHALEGHI FARIDEH
IPC: H04B10/08
Filed: 1998-08-27
Abstract: The BER is used as a parameter for evaluating the performance of an optical transmission system. Performance of optical systems is also defined by the Q factor, which indicates the signal-to-noise ratio of the electric signal regenerated by the receiver. In the absence of distortion, Q is univocally determined by the BER. Q is calculated using an estimated BER measured with the path under normal conditions of operation, and a distortion-free Q is determined in the same operating point of the system. The distortion penalty for the path is obtained by comparing the measured Q with the distortion free Q. In addition, the distortion penalty for a transmittter-receiver pair, and a distortion penalty for a transmission link between the transmitter and receiver may be determined.

Inventor: SCHULTZ ROGER L
IPC: E21B49/08
Filed: 1998-09-22
Abstract: A non-flashing fluid sampler for use in obtaining a well fluid sample. The sampler comprises a body defining a first chamber, a second chamber, a third chamber and a sampling port therein. The sampling port is in communication with the first chamber and with an outside zone outside the body. The second and third chambers are initially isolated from one another by a control valve. Upon activating the control valve, fluid may flow from the second chamber to the third chamber through a flow restriction. An extendable floating piston is disposed between the first and second chambers, and the floating piston defines a variable volume therein. An initial amount of well fluid flows into the variable volume, thus trapping dirty fluid, and subsequently, a well fluid sample is flowed into the first chamber. An isolation valve is provided for allowing hydrostatic pressure into the sampler after the fluid sample has been taken. Check valves prevent outward fluid flow from the sampler and thereby trap the hydrostatic pressure therein. Methods of use of the sampling apparatus are also disclosed.
